SHADE-ROLLER SUPPORT.

`Specification of Letters Patent. Patented lwal. 26, 1918.

Application led September 25, 191'?. Serial No. 193,149.

To all 'whom t may concern." l

Be it known that I, WALTER F. AYARs, a citizen of the United States of America, residing at Bridgeton, in the county of Cumberland andV State of New Jersey, have invented Ynew and useful Improvements in VShade-loller Supports, of which the following is a specification.

The invention relates to window shade xtures in general but is particularly a support for shade rollers. Its principal object is to provide a device of this character so constructed that it may l be easily and quickly applied to window Y ed to grasp the window frame on both sides thereof and to provide means whereby these plates may positively connect after' being made to engage the window frame.

Still another object is the provisionof a pair of hingedly mounted shade roller supports (these supports being attached one to each of the aforesaid plates), so that the supports may be made to lie down Vagainst the plates when not in use.

Still another object is to provide a device of this character which may be easily and cheaply made and which will be durable and effective in use.

As the device is set forth in detail in the following description, other and further objects will appear.

To the specific embodiment shown and described. the invention is not to be restricted. The right is reserved to make any changes or alterations which practice may suggest, provided such changes or alterations` do not depart from the spirit of the appended claim.

The same numerals of reference designate the same parts throughout the several figures of the drawings, wherein:

Figure 1 is a front elevation of the invention applied to a window casing.

Fig.2 is a longitudinal sectional view of the structure shown in Fig. 1.

Fig. 3 is a section on the line 3-3 of Fig. 1.

Fig. 4 is a view looking down upon the support 7 and its attendant pivotal supporting pin.

Fig. 5 is a section on the line 5-5 of Fig. 1,

Fig. 6 is a detail collective perspective view showing the interconnecting teeth of the plates 1 and 3.

Referring to the drawings, there isshown a plate 1 having a hook portion` 2 formed at its end. A plate 3 coperates with the plate l and it has a hook portion 4 at its end similar to the hook portion 2. Each of the plates 1 and 3 have ears 5 attached to it, each pair of ears being designed to support a shade roller support closely approximating the conventional form of such support. The ears 5 on the plate 3 hold in pivotal engagement between them the support 6, while those ears on the plate 1 similarly hold between them the support 7. Both the supports 6 and are pivotally supported on pins 8 which are attached between their attendant ears 5 and each support is provided with a pair of integral lugs 9 adapted to contact with the ears 5 when the supports are positioned at right angles to the plates 1 and 3 respectively. The ear lugs 9 preclude the movement of the brackets 6 and 7 further than right angles with respect to the plates 1 and 3 but do nct'prevent the folding of the brackets against the faces of the plates.

The plates 1 and 3 are adapted to overlap each other at the ends remote from those on which the hook ends are formed and these overlapping ends carry each a series of teeth 10, the teeth on the plate 1 being on its front face and the teeth on the plate 3 being on its back. Both sets of teeth 10 are diagonally disposed but the angle of inclination of the teeth 0n the plate 3 is the opposite to that of the teeth on the plate 1. By this means the two sets of teeth are enabled to effect a hook engagement with each other and thus Securely attach both plates to the window casing after the hook ends 2 and 4 have been made t0 engage the sides of the said casing.

The teeth. on the plate 1 are cut away on a line coincident with the transverse center of the plate, thus resulting in the formation of the slot 12 which obtains at the longitudinal centers of the teeth and runs in the direction of the length of the plate. A series of uniformly spaced holes 13 is formed in the center of the slot 12 and these holes may or may not pass entirely through the plate 1. A block 14 is set in the plate 3 and is adapted to slidably engage the slot 12, the teeth 10 formed on the plate 3 having their ends abut this block on either side and extending from the block to the top and bottom edges of the plate. A series of holes 15 is formed in the block 14 but these holes are truste-conical in shape, the smaller base `of the frustuni opening on the front of the plate 3 and the larger base facing the slot 12.

The object of this arrangement is to permit the use 'of a tapered pin 16, shown in.

dotted lines in Fig. Q to be inserted through the smaller end of any one ot' the holes 15 and made ,to Vdiag-( i nelly engage one of the holes 1B. The operation of straightening the pin lthen results in drawing the plates 1 and 3 towaideach other, causing the tivo sets ot' teeth 10 to yratchet over one another and effeet a tight clamping operation of the hook endsofthe two plates on the Window casing.

The arrangement for having the block 15 slidably engage the slot 12 operates to keep the plates 1 and in substantial alinement with each other.

yWhen Ithe brackets 6 and 7 are not in use they may be folded down in their respective places as before described.

Ijlaving once been attached to a Window frame, the device as `aivhole may be easily removedtheiiefroln by the simple operation of prying theJ plates l and 3 apart, thus disengaging the two sets of teeth 10 and releasing theelamping hold which the hook ends of the plates had on the Window frame.

The invention having been described what is claimed as new and useful is:

The combination, in a shade roller support, of a air of plates each having a hook end, the p ates'overlapping at' the ends remote from the hooks, Said overlapping ends beingprovided With interlocking teeth, one of the plates being provided with a longi,u tudinal` slot running through the centers of its teeth, a block carried by the other of the plates and slidably engaging said slot, the first plate having a series` of uniformly spaced holes formed in the bottoni of its slot, the block being provided With a series of runiformly spaced .busto-conical shaped holeswhose larger openings face the holes in the aforesaid slot, and means carried by both the plates for lsupporting ay'shade roller between theni.

In testimony whereof I aiiy my signature.

WALTER F. Avans.
